Use these colorful PDFs to assess students' prior knowledge of mean, median, mode and range.
Consider counting off by 4's, and asking each student to complete one organizer individually, knowing they will group with others who worked on the same term after a few minutes.
Then, group students in "expert groups" of students who all had the same term, to hear one another's ideas and add to each organizer.
Finally, consider having a representative from each group present his/her organizer to the class. Or, "jigsaw" and have one representative from each group join to make groups of 4 such that every student has a completed organizer for all 4 terms after each "expert" presents.
The full color pages would be best used as PDF files on a device like iPad. Included for your use are black-and-white copies better suited for photocopying as well.
No keys are included, as these are designed to be student created for brainstorming and assessing prior knowledge and/or misconceptions, as many students mix up these terms!
